This CanadaMeteoWCS data import is used for targeted access to gridded Numerical Weather Prediction and re-analysis data from the Meteorological Service of Canada (MSC) GeoMet Services.
Specifically a Web Coverage Service (WCS) returns a netCDF file from a structured url query.
This data import is available since Delft-FEWS 2018.02 and a patch more recent then January, 2020. Since version 2022.02 it is possible to access data that require authentication with username and password
The data can be downloaded on the same grid as DataMart is not subsetting is requested. If subsetting is requested, than a different grid will be requested.
Instructions for Creating a Subset Grid are provided at the near the end of this documentation.
1) Data Provider Documentation
This service is hosted by the Meteorological Service of Canada:
For an overview of the Web Coverage Service, refer to: https://eccc-msc.github.io/open-data/msc-geomet/web-services_en/#web-coverage-service-wcs
For a complete and update to late list of available data types, refer to: https://geo.weather.gc.ca/geomet?SERVICE=WCS&VERSION=2.0.1&REQUEST=GetCapabilities
The license of the data provider (Environment and Climate Change Canada) can be found here https://dd.weather.gc.ca/doc/LICENCE_GENERAL.txt
2) Example Configuration
The example configuration is for the Global Deterministic Prediction System (GDPS) numerical weather system for the TimeseriesImportRun followed by IdMapping and Grid definitions for a wide variety of imports.
Also included is the cardinality of workflows.
The two variables accessed are precipitation (PC.nwp) and temperature (TA.nwp).
Reference to NWP
Notice that the reference to the NWP is not included in the URL, as is often the case with server imports, but is included as part of the IdMapping (externalParameter)

Property subsettingCrs is optional. If not configured, the "&SUBSETTINGCRS=EPSG" will not be added to the url.
Property useSubset is optional. Default value is true. If set to false, no subset will be added to the url. Values will be pulled from the configured grid.
Properties interpolation, outputCrs,rangeSubset are optional. If configured, INTERPOLATION=configuredValue, OUTPUTCRS=configuredValue, RANGESUBSET=configuredValue will be added to the url, respectively.
Property delayInHours is optional. If configured DIM_REFERENCE_TIME=date will be aded to the url, where date is T0-delayInHours.
TimeseriesImportRun (Ensemble Forecast with 21 members)
The configuration code below is for the REPS Ensemble Forecast with 21 members.

Cardinality of Workflows
As the forecast requests are issued at specific intervals, a CardinalTimeStep is needed.
The examples below (and following Timestep definitions can be used to ensure the requests are made at the correct hour.

3) Instructions for Creating a Subset Grid
To create a smaller grid, follow these steps:
1) Define the bounding box coordinates (https://boundingbox.klokantech.com/, try Dublincore below Copy and Paste for clarity)
2) Fill in the url query below:
https://geo.weather.gc.ca/geomet?SERVICE=WCS&VERSION=2.0.1&REQUEST=GetCoverage&COVERAGEID=$VARIABLE_ID$&SUBSETTINGCRS=EPSG:4326&SUBSET=x($westlimit$,$eastlimit$)&SUBSET=y($southlimit$,$northlimit$)&FORMAT=image/netcdf
where:
$VARIABLE_ID$ is from the WCS getCapabilities, or from the externalIDs in this document.
$westlimit$, $eastlimit$, $southlimit$ $northlimit$ are an integer bounding box
3) Paste the query in a webbrowser to download a sample file.
4) In your FEWS application, use the functionaility from the F12 menu --> Clipboard --> Copy grib geometry from file.
5) Paste the grid definition in your grids.xml file. Save and reload FEWS.
6) Run the workflow in DEBUG mode to get the url query generated by FEWS.
7) Use this FEWS generated URL query in a browser to download an additional NetCDF file, then repeat steps 4 and 5.
4) Known issues
No known outstanding issues.
